run code in 300+ PHP versions simultaneously
<?php class x { function z() { static $x = 2; return $x++; } } $x = new x; var_dump($x->z()); var_dump($x->z()); var_dump($x->z());

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
